Iso-Wall System

Regardless of whether you have a professional "downtown" studio project, or a dedicated theater/audio room in your house, ASC's Iso-Wall and Iso-Ceiling soundproofing is the only way to go.

Our entire line of Walldamp+Iso products are engineered for optimal musical acoustic quality, both live and playback. When music quality matters and room acoustics are critical, every recording studio project starts with soundproofing. ASC's award winning acoustic products start with our Walldamp+Iso and WallDamp soundproofing systems for walls and ceilings. In our humble opinion, there is no better product for recording studios.

Whether you are building a recording studio, dedicated home theater, or simply looking for superior sound insulation, nothing works better than ASC Iso-Walls. This unique construction system has been developed over 15 years in the design and building of professional recording studios. Now, this proven system is fast becoming a requirement in the construction of custom home theater and hifi audio rooms.

Today's home entertainment systems, with large subwoofers, have as much explosive bass power as found in most recording studios. Typical construction methods are simply not adequate for handling these high dB levels. The IsoWall system was designed from the onset with high-level musical playback in mind.

How It Works

Keeping Sound From Traveling Through a Structure

There are three methods:

  • Block the sound by increasing the mass (thickness & density) of the walls & ceiling.
  • Minimize the transmission paths for vibrations and sound to travel though.
  • Absorb & damp vibration energy throughout the structural elements.


ASC's proprietary Iso-Wall System incorporates all three of these methods:

  • More than doubles the Mass
  • Isolated "floating" wall & ceilings
  • Walldamp vibration absorbing compounds used throughout


The ASC Iso-Wall uses a proven soundproofing method called resilient channel to isolate the interior walls of a room. We then improved the idea by adding low frequency sound damping and vibration control. The result, installed in hundreds of high end audio rooms, is the only soundproofing system engineered for high volume audio playback.

By utilizing our proprietary WallDamp material (a visco-elastic polymer) throughout the system, low frequency sound energy is absorbed into the wall. This reduces bass feedback and shuddering walls, and results in a clean, rich sound with well-balanced frequency response.



With the Walldamp Iso-Wall System, you get walls & ceilings that reduce sound transmission by 20dB or greater compared to standard interior walls. That is more than quadruple the perceived sound volume reduction, which is what makes our wall system the highest available using standard single-stud construction. Internally, the walls are tempered to move with the air pressure of bass frequencies. Where a rigid wall would shudder at high volumes (similar to the distortion in an overdriven speaker) and raise the noise floor of the room considerably, an IsoWall will "bend" with the pressure and absorb the sub bass sound wave while allowing the bass waves to reverberate cleanly. 


Typically, we estimate the cost of IsoWall at $5-7 per sq ft, with larger rooms generally providing a lower cost per square foot.  Here are three common examples:

Consider a 20' x 14' x 9' dedicated HiFi listening room with one standard size (30" x 78") entry door and three 6' doors and three picture windows sized 24" x 48".  The IsoWall components for this room would cost about $4,200.

Consider a 24' x 17' x 11' Control Room + Mastering suite with two equipment-ready doors sized 3' x 7' and a large window (4' x 5') into the vocal booth.  The IsoWall components for this room would cost about $5,850.

Consider a 13' x 10' x 8' bedroom studio/theater/listening room with a single entry door (30" x 78") and a side bathroom door (28" x 78") plus two exterior single hung windows sized 20" x 36".  The IsoWall components for this room would cost about $2,400.

IMPORTANT NOTE:  The IsoWall package does NOT include drywall or fasteners.  Please support your local economy by sourcing these from your nearest interior supply house.
